I HATE VODACOM....Z

I bought my phone cash in 2016 at vodacom and I insured it,I have been paying insurance until this today. I ported to telkom in 2018 nd nobody told me that I wasn't supposed to port,so last week I got ****** nd I went to the police station to get a case number and I went to claim only to find out that apparently my number doesn't exist but vodacom have never stop deducting and on their system it shows that my insurance is up to date. So they can't reimburse me m very disappointed with VODACOM SERIOUSLY. They could've stopped deducting in 2018 cuz according to them my number doesn't exist but I hv kept the number but I just ported to another network. I could have went to cell c nd insured there.
